There are more than a couple issues to work out when inventing space beer. You can't just grab a Todd the Axe Man and head to space. Alcohol absorption is different in space. (The team drank beer in zero gravity as a part of the testing process.) Carbonation doesn't work the same. There's something horrible called a "wet burp." Pouring is, well, not a thing.
They've conquered some of these problems, settling on a dry Irish stout with seven malts and a 5.1% ABV. The beer has won awards in Australia, but the beer may have been the easy part. Vostok didn't want to put beer in the kind of squeeze pouch astronauts use for water or juice. Instead, they came up with a space-age-looking bottle that essentially works like "fuel tank technology." The scientists behind it used fluid dynamics and surface tension to create a bottle that wicks beer into the neck. On the bottom of the bottle is a cup that can be a little souvenir to bring back to earth when you land.
